Taylor Swift joined by ‘heroes’ Joan Baez and Julia Roberts during California

Taylor Swift’s friendship squad continues to expand night after night during the 1989 World Tour.

In addition to the Little Mix babes, Taylor was also joined on stage by American folk music star, Joan Baez, and, rather randomly, Julia Roberts who appaz “danced it out to “Style“.

Taylor collaborated with Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock, and Jade Thirlwall to perform the group’s single “Black Magic” at the Levi’s Stadium.

If Taylor Swift’s 2015 has taught us anything about the mega-selling pop starlet, it’s that she is a friend-collector par excellence.

“LITTLE MIX!! Love these girls!!”

The 25 year old was equally excited by her company, sharing snapshots over on her own social media accounts, exclaiming: “LITTLE MIX!!”

Swift shared a picture on Instagram of herself and Little Mix on stage.

“How do you feel”, Taylor demanded of her audience when the song was finished, “that Joan Baez and Julia Roberts came by to say hi to you tonight?” “They smashed it tonight in front of 50,000 screaming fans”, Swift wrote on Twitter after the show. And when we saw Swift perform in our hometown, the guest star was none other than Jason Derulo, so these two just seemed like an odd choice.
